I want to HTTP request with dynamic parameters, so I created a CSV Data Set Config. This is a CSV Data Set Config example:
CSV DATA SET CONFIG
"lat";"lng"
40.9912941561618;28.7894749639963
41.0824834;28.9850201
41.0611814136864;28.030526752118
41.0001116337;29.1471918672
40.9840449469281;28.868293762207
41.0062257041343;28.6599397659302
40.9870953373281;28.8735637664795
40.9842483906616;28.8679887067701
HTTP REQUEST
Server name is example.com. Delimeter is ;.
Dynamic parameter path is v1/ej/log/geojson?lat=${lat}&lng=${lat};
CSV Data Set Config
When I sent request it doesn't set the parameters. How I can do ?
CSV Data Set Config is by default a Comma Separated Values. In your file it's ; Separated, so you need to define Delimiter as ;.
Also remove quotes for first line with variable names:
lat;lng
And make sure you set the flag
Use first line as Variable Names
Ignore first line of CSV file, it will only be used used if Variable Names is not empty, if Variable Names is empty the first line must contain the headers.
Values are stored as JMeter variables and used as: ${lat} so your path should be
v1/ej/log/geojson?lat=${lat}&lng=${lng}

I am trying to parameterize my request using CSV Data Set Config. My input includes double quotes("), colon(:) and brackets([])
Eg: fiscal_year ":["2021",2019]"
Had tried with it, but in the actual results its passing as "fiscal_year "":[""2021""
Please share your inputs on what am i missing on the input paramter.
I don't think it's due to double quotes("), colon(:) and brackets([]), CSV stands for comma-separated values so JMeter treats it as a delimiter and reads everything including to the first comma.
So you might want to change the "Delimiter" to something else:
It's hard to come up with a comprehensive solution without seeing at least couple of lines from your CSV file and the way you're parameterizing the HTTP Request with JMeter Variables
In case you have one entry per line in the CSV file it might be easier to go for __StringFromFile() function which reads next line from the file each time it's being called. See Apache JMeter Functions - An Introduction for more information.
I have a value in a "pro va" csv file that must be passed to a query of a URL "google.com/search?q=pro%20va" I would need to replace the space with% 20 from the variable taken from the csv, how to do it ?
Space isn't allowed in HTTP GET path or query.
You need to encode query parameters that contain spaces. Some options as below:
Check "Encode?" box in "Send Parameters with the Request" input of HTTP Request
Wrap your variable in __urlEncode function as ${__urlencode(queryTerm)}
http request default. http request config. csv data config used. csv data file used .I wanted to add data from csv file, but if i pass single parameter also its adding "&" character before parameter.
ex: https://www.linkedin.com/start/join?&name=A0A1A0
Just remove this ? sign from the /api/dealer/searchByPostalCode
JMeter automatically detects query string beginning in the URL path and tries to merge parameters with the ones you specify in the path to avoid syntax errors.
Given you don't provide any parameters in the "Path" section you should remove ? from there.
Another possible reason is that your CSV data contains this & character, double check it using Debug Sampler and View Results Tree listener combination.
As per the official documentation:
As a special case, the string "\t" (without quotes) in the delimiter
field is treated as a Tab.
When the end of file (EOF) is reached, and the recycle option is true,
reading starts again with the first line of the file.
Source: http://jmeter.apache.org/usermanual/component_reference.html#CSV_Data_Set_Config
So I'd request you to remove \n in delimiter field from the CSV Data set config and then try.
I am using JMeter 5.1.1.
I have a CSV file looks like this
When I call HTTP Request like this
I get this
Jmeter doesn't take the value but just pass the name of the variable to the URI.
But if I take the second column CustomerParam by putting ${CustomerParam} , then JMeter will grab the value (instead of the name of the variable).
I am wondering how can I get the values of the first column ?
Thanks.
I found the root cause.
When creating the CSV file using the newest Microsoft Excel 365 , save it as CSV , not CSV UTF-8.
When I saved the file using CSV, JMeter works perfectly fine. But when I saved it using CSV UTF-8, then the issue I described earlier does appear.
If Variables are referenced as follows:
${VARIABLE}
If an undefined function or variable is referenced, JMeter does not report/log an error - the reference is returned unchanged. For example, if UNDEF is not defined as a variable, then the value of ${UNDEF} is ${UNDEF}.
Input the Variable name in your CSV Data Set Config as follows (If your CSV data set looks exactly above where variable names are present in the first line):
Or, you can just remove the variable names from the first line of your CSV file and make the config as below:
I cannot reproduce your issue using the same CSV Data Set config:
The evidence that the variables have been read (assumes Debug Sampler and View Results Tree listener combination)
So double check the following:
Your CSV file integrity as it might be an issue with the data itself, i.e. if there is a BOM at the beginning - you will have to remove it as the BOM will be added to the first variable name (use aforementioned Debug Sampler and View Results Tree listener to verify which variables are defined)
An problem with the CSV file operating-system wise (i.e. typo in location or file permission issue). Normally JMeter should report any errors connected with failure of reading the CSV file in jmeter.log
Using JMeter to support functional API testing and have run across a problem with reading data from a CSV file. The data from the file is used in building a POST data body which contains something like this:
"wibbles" : ${wibble-var},
${wibble-var} is read from a CSV file and has the format :
["wibble1","wibble2","wibble3"]
... there are over 1000 wibble values in the list.
If "wibbles" : ["wibble1","wibble2","wibble3"]... is hard-coded into the POST body, then JMeter is happy, builds the POST request and does the business, but it's proved impossible to create a CSV file with even the 3 value example above, that JMeter will parse. JMeter skips the thread containing the 'CSV read' without building the POST request or sending it, so there's no response to examine, and a Debug Sampler is similarly skipped. I've heard rumours that doubling up the quotes can work but haven't been able to find the right syntax. Can anyone throw any light on this issue? Thanks
Double quotes will work if you can get "wibble1,wibble2,wibble3" & if you set Allow quoted data to true in CSV data set config
You can get this value and then use beanshell preprocessor to convert to the format "wibble1","wibble2","wibble3".
If you want to get in this format "wibble1","wibble2","wibble3" directly, you can use \t as the delimiter & modify the data in the CSV file accordingly.
Trial and error led to the following solution.
The format of the single data variable I needed to parse is ["value1","value2","value3"] (i.e a JSON array.) and this is exactly what the CSV file contained (with a header name of course on the first row), including the [ and ] brackets.
I modified the parameterised POST body to:
"wibbles": [${wibble-var}],
-- that is, I moved the square brackets out of the CSV file so that the CSV file now just contained the quoted elements of the array:
"value1","value2","value3" etc
I then set the delimiter in the CSV Data Set Config to |
And Allow Quoted Data to FALSE. <--- This was a bit counter intuitive but without it JMeter would not read the whole comma separated list of 2000 quoted strings as a single variable.
With these changes in place the script executed correctly.
Thanks again for the responses, I will definitely look at the __String functions mentioned.
I would go for the following options:
If your "wibbles" are a single string which you need to pass a a JSON Array it might be a lot easier to access them via __StringFromFile() or __FileToString() functions like:
"wibbles" : ${_StringFromFile(/path/to/file/containing/wibbles,,,)},
If you need to access individual "wibbles" and your CSV file is basically a JSON file:
Add HTTP Request Sampler to your test plan (before one which sends these "wibbles") and configure it as follows:
Protocol: file
Path: c:/testdata/yourfile.csv
Add JSON Path PostProcessor and use a JSON Path query to store the "wibbles" into a JMeter Variable(s)
